Buzzing/Rattle at 2k-3k

[KYAWD]

It seems like when it warms up there is a buzzing noise coming from timing belt area from 2k-3k.I was thinking bearings but just not sure the sound comes and goes any ideas?

Well if you know its coming from that area, i would visually inspect it, pull cover off and see if anything looks out wack. Very hard to say no video, or anything else?

Ill try to take a video I just didn't know if anyone has had this problem.

I havent if i did i would stop the car and have it towed, not knowing what it could be, another head job isnt fun or cheap.

I would say pull the timing cover and check the idler and other pulleys for any play. There's only so many things on that side that it could be.

Auto tensioner could be on it's way out or the plunger of the tensioner might have worn a divot where it contacts the tensioner arm. Either of these situations could allow the tip of the tensioner arm to contact and bounce off of the top of the auto tensioner.

Also check your exhaust heat shields.

Could the balance shaft be 360* off?

It just started doing it I'm thinking its timing belt bearings.
